Maintenance WARNINGS Do not put engine coolant in the windshield washer fluid container. If sprayed on the windshield, engine coolant could make it difficult to see through the windshield. To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure. Steam and hot liquid can come out forcefully when you loosen the cap slightly. Do not add coolant further than the MAX mark. Note: If the level is at the MIN mark, below the MIN mark, or empty, add coolant immediately. Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -30°F (-34°C) and -34°F (-37°C). Note: For best results, coolant concentration should be tested with a refractometer such as Robinair Coolant and Battery Refractometer 75240. We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentrations. Note: Automotive fluids are not interchangeable. Do not use engine coolant, antifreeze or windshield washer fluid outside of its specified function and vehicle location. As long as the engine coolant is clear and uncontaminated, this color change does not indicate that the engine coolant has degraded, nor does it require that qualified personnel drain the engine coolant, flush the system or replace the engine coolant. Do not mix different colors or types of coolant in your vehicle. Mixing of engine coolants may harm your engine's cooling system. The use of an improper coolant may harm engine and cooling system components and may void the warranty. Use prediluted engine coolant meeting the Ford specification. See Capacities and Specifications (page 290). In case of emergency, you can add a large amount of water without engine coolant in order to reach a vehicle service location. In this instance, qualified personnel: 1. Must drain the cooling system. 2. Chemically clean the coolant system with Motorcraft Premium Cooling System Flush. 3. Refill with engine coolant as soon as possible. Water alone, without engine coolant, can cause engine damage from corrosion, overheating or freezing. Checking the Engine Coolant When the engine is cold, check the concentration and level of the engine coolant at the intervals listed in the scheduled maintenance information. See Scheduled Maintenance (page 392). Note: Make sure that the coolant level is between the MIN and MAX marks on the coolant reservoir. Note: Coolant expands when it is hot. The level may extend beyond the MAX mark. Adding Engine Coolant Note: Do not use stop leak pellets, cooling system sealants or additives as they can cause damage to the engine cooling or heating systems. Your warranty may not cover these damages. Note: During normal vehicle operation, the engine coolant may change color from orange to pink or light red. 241 MKS (), enUSA
